ASK YOUR TEACHER At Burnt Mesa Pueblo, archaeological studies have used the method of tree-ring dating in an effort to determine when prehistoric people lived in the pueblo. Wood from several excavations gave a mean of (year) 1230 with a standard deviation of 30 years. The distribution of dates was more or less mound-shaped and symmetric about the mean. Use the empirical rule to estimate the following. (a) a range of years centered about the mean in which about 68% of the data (tree-ring dates) will be found between and A.D. (b) a range of years centered about the mean in which about 95% of the data (tree-ring dates) will be found between and A.D. (c) a range of years centered about the mean in which almost all the data (tree-ring dates) will be found between and A.D. MY NOTES
Question 7 く > A Gallup poll wants to determine the mean number of books Americans read each year. How many subjects are needed to estimate the average number of books Americans read with a margin of error of 0.6 books with 95% confidence? Initial results of the Gallup poll indicate that the population standard deviation is 5.8 books. Round your answer up to the next integer.
IQ is normally distributed with a mean of 100 and a standard deviation of 16. A local school is considering what its minimum IQ score should be for admission. What should the minimum IQ score be so that 90% of all students in the area can qualify for admission? How can I calculate this using Excel or by hand
People were polled on how many books they read the previous year. Initial survey results indicate that s = 14.3 books. Complete parts (a) through (d) below. Click the icon to view a partial table of critical values. GOLDA (a) How many subjects are needed to estimate the mean number of books read the previous year within four books with 90% confidence? This 90% confidence level requires 35 subjects. (Round up to the nearest subject.) (b) How many subjects are needed to estimate the mean number of books read the previous year within two books with 90% confidence? This 90% confidence level requires 139 subjects. (Round up to the nearest subject.) (c) What effect does doubling the re accuracy have on the sample size? OA. Doubling the required accuracy nearly doubles the sample size. B. Doubling the required accuracy nearly halves the sample size. C. Doubling the required accuracy nearly quadruples the sample size. D. Doubling the required accuracy nearly quarters the sample size.

QUESTION 12 You hypothesize that drinking water increases test scores so you design a study comparing test scores between people who drink water and people who do not drink water.You collect data on 62 people and find that in your sample there are 27 people who do not drink water and 35 people who drink water. The mean test score for non-water drinkers is 62 with a standard deviation of 13, while the mean score for those who drink water is 75 with 11 standard deviation. Above you have calculate the t-statistic and found the critical value of t. Based on this information, is the difference between your two means STATISTICALLY SIGNIFICANT? OYes, because the t-statistic value calculated was less than the critical value of t, indicting that p .05 O Yes, because the t-statistic value calculated was larger than the critical value of t, indicating that p .05
